text: Albertus Magnus  ( – 15 November 1280), also known as Saint Albert the Great, Albert of Swabia
  or Albert of Cologne, was a German Dominican friar, philosopher, scientist, and bishop, considered one of the greatest medieval philosophers and thinkers. 
  Canonized in 1931, he was known during his lifetime as Doctor universalis and Doctor expertus; late in his life the sobriquet Magnus was appended to his name. Scholars such as James A. Weisheipl and Joachim R. Söder have referred to him as the greatest German philosopher and theologian of the Middle Ages. The Catholic Church distinguishes him as one of the Doctors of the Church.
